Sam Bigelow 066a99b6e9 Add markdown buttons to file editor
Currently, we have markdown files in many places (e.g. comments, new
issues, etc.). This Merge Request detects if the file being edited is a
markdown file and adds markdown buttons and their functionality to the
single file editor (Not the web IDE)
